i i Application led September 29, 1925. `Serial No. 59,303.

This invention relates to improvements in a mechanical means fortransmitting power, the principal object being to transorm a rotarymotion into a reciprocatory one and to extend the reciprocationindefinitely.

A further object is to provide a mechanism utilizing cooperating racksthat mesh with block encased gear wheels, such blocks and racks beinginterrelated in a train;

To .the accomplishment of these and related objects7 my inventionresides in the construction, combination and arrangement of parts asshall be hereinafter more fully described, illustrated intheaccompanying drawings and (pointed out in the claiu'is hereunto appendei The invention` can be most clearly de scribed and most readilyunderstood when reference is had tothe accompanying illustrations of the`preferred (,:onstruction in which:

Fig.1 is an elevation of the train of gear carrying blocks and racks,part being shown Si in section;

Fig. 2 is a fragmentary plan;

Fi 3 and 4 are elevations ot the rack and lsock reciprocatingmechanism.`

Fig.5 is an alternative form of recipro- 8 eating mechanism;

Figs. 6 and 7 are vertical and horizontal sections respectively, astaken on lines 6 6 and 7-7 of Fig. l; and

Fig. 8 is a section through `the lower rack y and supporting track.

" `In this invention for thetransforming of rotary motion intoreciprocatory and the unlimited extension of the reciprocations, I em-`ploy gear wheels encased in blocks or car` n riagesthat are connected ina train by racks,

meshing with the gearr'wheels, that are also mounted on the blocks. y

of interconnected blocks `are arranged in alignment and all ride onamain' rack, mesh-` ing with the gears, thatis reciprocated. The firstblock in the series carries no rack but the encasedgear meshes With therack from the second block Whose enclosed gear receives inturn the rackmounted on the third block and so on.

The mechanism producing the reciprocations of the train of gear blocksand of the main rack which are opposed, differs depending on the natureof the source of 5I power: If rotary, a shaftwith collars riding Theseries or train on reversed threads is used and the shaft oscillated bya segmental crown gear acting on a pair ot spaced pinions keyed to theifar end of the threaded shaftcrit reciprocatory andv paralleling thetrain, by fixed or rigid and pivoted lever arms that-connectrespectively with the end gear block and main rack.

Referring more xparticularly to the drawings wherein like charactersindicate like parts throughout the several views, 10is a suitable baseou which a trackll is positioned to support a rack 13 that is adaptedtoV reciprocate horizontally.' A number of blocks 14 straddle this rackwithin each of which is enclosed a gear wheel 15 that meshes with therack 13 andrides thereon supporting the block in this Way. A- channel16xis cut through the blocks near thetop from end to end and is sodisposed with relation to the enclosed gear that a rack member 17 deisigned to pass therethrough may contact with the said gear.

The rack 17 is carried by that block 14 immediatelybehind the blockencasing the gear Wheel Withwhich it contacts and is ap-4 plied to theblock by fastenings 18 on each side, Athe rack piece being bifurcatedand formed to laterally engage both. sides ot the blockfas shall be morefully described.

f It Will thus be seen that the train of inter-` connected blocks 14 andthe main rack 1.3 are both adapted to reciprocate horizontally and sothe maximum ot efficiency is to be ob tained from this mechanism bycausing these parts to recxprocatefin opposite directlons.

Toaccomplish this I provide a shaft 19 an fend of which is threaded lettfor a space and then threaded right asl at 20a and 2Gb respectively andto these reverscthreads are applied collars 21 and QZffrom the former ofwhich a standard extends to connect with the reciprocable rack 13 `whilean arm spaced from and paralleling the axis of theA latter is fixed tothe block 14 on the near end of the train. The end of the shaft' remotefrom the threads carries a pair oi'ispaced pinions Q3 vthat meshWithopposite sides ofthe-same face of a segmental crown gear 24supplying the power in this instance. The crown however is" toothedthrough `less than ahitlf of its circumference so that on turning0pposite rotations are imparted to thel shaft 19 byV its meshing withfirst onepinion and then the other. At suitable locations throughout itslength the shaft i is supported by bearings 25 on standards 26. a Asieobvious this type of reciprocating mechanism-"can only lie-employed whenthe power is being supplied in the rotary i'orm,`

I have included a modification to operate the device when areciprocating source is to be utilized. This, as shown in ig.- 5,comprises,

a shaft 27 reciprocating in a plane parallel -With theV transmission, arigid arm 28 tlierefrom fixed Ato theend blockll anda' cen-,trallyzpivoted lever 29 connected to theend of the main rack 13, thepivoted connection on each end thereof including a pintle rei5 eeivingslot. i f i The racks 13 and k17 to which reference is made in theprecedin Will preferably be in A the form ol channels ctween whoseupright sides little rollers 30 are arranged transy versely. i y

f In the case of the rack members 17 the base of the channel ispartially removed to form a fork, that bridges the block to which it isapplied and fastened thereto as described. z5 The lower orniainrack,havingr toreciprofcate `on the track 11 is recessed to receive the .ivsame .by haviiigtlie bottom of'` the ,channels raised between f thearms thusuforming a t, double thickness of. side for a part `thereof'and then havingthe lowermost edges bent inwardly andksecurely and snuglyembracing the rail. Friction is reduced by the insertionof rollerbearings lvbetween the underside ofthe channel base andfthe` track.V iIn operation7 when the required number of gear carrying blocks orelements have been i .arranged in line and means for oppositelyreciprocating the blocks and main rack'liave been connected, theendblock, remote from iexthati'receiving the reeiprocations is movedbackand dbi-th a` distance proportionate to4 but'many times greater thanthe first block i e. g., if the firsty block is advanced one inch andthemainirackimoved the same distance ein the oppositedirection, Athe secondgear blockis advanced" three 'inches the third sixy `inclfiesjand so onfor it `will befobserved that., if the'inainrack' was fixed and thefirst block Y vvadvanced one inch the second block would 5U .move a;like distance without the action of the gear and rack but with Vthis theygear is rotatedrby contact with the fixed lower rack and thisrotationadvauces the rack member `.fixed tothe second blocktherebyiidrawing GCN-the said :block upfanotliei-yinch, making a` 'total,of two' inches: The ratio being as a nrizif) :2(2a) :2(4a) etc.; whilethe opfposite reciprocation of the main rack still xfurtlier` advancesthe blocks, excepting the first, ingthe proportion of b :2b 3b etc. Thismovement in like increasing relation is trans- 1 mitted to eachsuccessive block element api pliedto; thetrain so that the multiplyingof @,m themovenient may be carried outl to any de sired extent,

From the foregoingdescription taken in connection with the accompanyingdrawings, it will be manifest that amechanical means for transmittingpower is.- provided ywhich Will-fulfillall the necessary requirements ofsuch a device, but as many changes could be madein `the abovedescriptionand many apparently widely ydifferent embodiments of my inventionconstructed within the scope of' the appended claims without departing`from the spirit or scope thereof, it is intend- Aed that all. matterscontained in the said accompanying specification and drawings shall beinterpreted as illust ative and not in la limited sense.
